Ilrondal

Ilrondal is the name the elves have assigned to the only lake south of the Lost Souls. This lake fills over two thirds of a cavern, fed and drained by the Gilfyn River. Upstream and east is the Citadel of Saulia and the large vault behind that. Downstream and west is the Elmglow side of the Lost Souls cavern.

That part not filled by the lake is on the western outflow. This ground is mossy, and on the bank is a "village": Gilaen. No more than two thousand elves inhabit this cavern.

I've taken a screencap of the 8mile-hex PDF map, expanded it, and overlaid white 2mile-hexes on that. It has about the area of the Boiling Lake, so ties with the smallest on the map. The DM may expand at will: if these are 4mile-hexes, the lake would be the size of Estenreth. Almost anything goes south of the desert.

This whole area is beyond the City's reach. I've proposed that the upstream is dark elf and (more forcefully) downstream, is dead. Ilrondal is no place for normal folk. The lake, then, is host to shadow-elf exiles and semiëxiles.

Farms dot the mossy plain to the north. South, less fertile, hosts a geonid tribe, numbering about fifty; as often for hunter-gatherers on the farming fringe, these have taken to slug herding. The "village" on the map hosts few permanent residents. Along the river are the pontoon and sometime trading post; also, some inns.

Most elves live on rafts upon the lake proper. Also, some wizards have carved out hollows in the walls of the cave above. Aloft the lake's north corner is an aerie for skinwings and their tenders. Not to say there are any, at present; but sometimes the army visits. The shamans have set an Ethereal barrier to the west.

Most geonids dislike the water. Their shamans have, however, experimented with fusing shells with pumice instead of the usual harder, heavier rocks. This pumice is imported (somehow) from the distant Red Rock Bellows far southeast. Some fifteen young geonids here are, as a result, able to swim. Also, they can move faster and bear heavier loads. Their armour-class is concomitantly worse than the geonid mean.

Open worship of Atzanteotl is not tolerated by either race here. Rafiel, too, is not much honoured, except by shamans. To the extent a libertarian shadowelf or civilised geonid exists, it's here.
